Description

Terrestrial fish farming filtration system

The review and development of the circulating filtration system has been under research for several decades by aquaculture workers in various marine research institutes, including the Ministry of Maritime Affairs and Fisheries.In Japan, since 1986, microbial purification has been mainly adopted. Although it is applied to practical use, it is known that the completion stage of this technology has not been achieved yet, and it is still under research and development.

The key to this circulating water purification system has been concentrated on the technology of how to quickly remove and purify fecal matter from dense fish groups, such as dust, and the like. The inventors came to realize that it is not.

It is from the view that as the reuse is repeated, the natural activity of the original water and the degradation of minerals gradually increase, increasing the risk of making the water unsuitable for ending use.

As environmental issues are mentioned due to the recent air pollution, the environment of fish is water. Even though the water is clearly purified, it is clear that the so-called water of water escapes, and the lack of minerals hinders fish growth. The present invention has been researched and developed mainly on the method of reactivating this reused water.

It is well known that the main role of the circulating filtration water purification system is the mainstream by the microorganism. As early as Masuda's study on Bacteria in a Rotating Disc with Rotating Discs (Sewerage Association Journal 24.1987), aerobic and anaerobic bacteria are present on a rotating disc, and their distribution and abundance There is a report that grasps the present, and based on this knowledge, the rotating disc is commercialized as a representative purification device (Utility Patent No. 18452), and it can be seen that it is widely distributed to real users.

Young-Cheol Jang shows this device in the test breeding announcement of the halibut farming in semi-closed circulation filtration system (Korean Journal of Fisheries Research, 28.1995) and attaches it as `` Facility for biological nitriding process ''. It was overestimated by a fully-resolved equipment lifting manufacturer, and it was an opportunity to spread to many real buyers, but the results still required a large amount of replenishment water. Odor generation is still not expected, so its penetration rate is slow.

It is well known that a large amount of oxygen (air) is required for ammonia nitrification. According to the preliminary findings, 4.57 mg of oxygen is consumed for nitriding 1 mg of ammonia, and the dissolved oxygen concentration (DO) of water is 4 mg / Below ℓ, the effectiveness of microbial filtration cannot be taken.

In such a situation that a large amount of oxygen is required, the structure of the rotating disc has revealed a limit on the amount of contact with oxygen (air) required as a passive means of indirectly exposing the rotating disc to the atmosphere.

Dr. Kim and his colleagues stated in `` Ammonia Removal Ability by Filtration Material of Seawater Circulation Aquaculture Facilities '' (Aquaculture Aquaculture 16.1997), "In regard to the ability to remove ammonia for one day per ㎥ of filter material, the water filtration tanks can use more air. In the case of the aeration tank (adjusted to DO 6-7), which is one of the active air contact methods, only about 2% of the oxygen content (approximately 1/4 of the air volume) of the injected air is actually consumed. In view of the preliminary findings of Japanese Patent Publication No. 60-3848, Germany: Werner Annex, etc., the ammonia nitrification is directly proportional to the large surface area and excessive amount of air introduced. In view of this device seems to be insufficient. Therefore, securing a large surface area increases the number of rotating disks described above based on the viewpoint of effectively attaching microorganisms (nitride bacteria) or various substrates (base materials: raw materials, ceramics, synthetic resins). Treatment method using a fibrous material). All of these were carried out on the basis of nitriding 150-300 g / day of ammonia nitrogen per 1 m2 of filter media, so the size of the facility was inevitably large. In short, there is a demand for the development of a substrate having a small size and having a large surface area, low cost, and reliable performance.

Recently, the term 'water activation' has been used in relation to water. Experts have found that water has long been known as a neutral immutable substance, but water also has a structure, n clusters of n 2 H ₂ O bonded by hydrogen bonds. ₂ O) has been found (see Fig. 3, 4).

The better the cluster is, the better it is for our taste and good for health. In Japan, the use of health and medical care is being promoted. Let's be. Dozens of manufacturers of various water softeners have been established and are competing for sales. (The Water Sciences Institute, `` The Latest Scientific Lecture on Science, '' 1995) Conversely, this cluster is largely related to tap water, which has worsened due to deterioration of water quality in Suwon. Rainwater, well water, river water, etc. are clearly identified by MRA (Magnetic Resonance Analyzer). In particular, once the used industrial wastewater is reported that the greater the pollution degree is larger and can not be noticed.

This is sufficient data to predict that the long-term reuse of the cultured circulating water will significantly change the clod clusters.

That is, the essential condensed milk which requires a large amount of supplemental water with the activity of natural water is pointed to this. No knowledge is available regarding these clusters' activities. The present invention has been politely examined in this regard.

There are several ways to activate water. In other words, the use of the magnetic field by the magnet implemented in the present invention, in addition to the electromagnetic field, electrolysis, ultrasonic vibration. Or various kinds of natural minerals (such as elvan, turmulin, etc.), all of which are expensive to install and require maintenance.

It has been reported that the dissociation (decomposition) of water molecules is promoted by the magnetic field energy and the cluster is extremely fine (about 1/10). (Emodo 江 本 勝 「Waves, water and life」 1995) And this effect is in the state of cluster like natural famous spring water, and it is delicious and active water, which is easily absorbed by the body and promotes metabolism, improving human's natural healing power. I will let you.

The industrial use of magnetic field energy has been made public since 30 years ago, with the provision of a number of technologies that attempted water treatment or fuel reform (reduction of fuel, reduction of exhaustion), which has been temporarily boomed, but all of them are now forgotten. Belongs to The records show this.

Dr. Dqn.D Carda, in a newsletter published by the WQA (Water Quality Association Canada) (October 1989), totally denied the effects of magnets in his research on water treatment devices, There was even a ban on entry to the WQA trade show.

Yoshimura conducted within 1000-3000Gs range in investigating the relationship between the strength and the effect of magnetic field in various tests on various fuels. It is believed that the cause of disbelief was that they did not know this phenomenon, saying that they found that the higher the magnetic field, the wider the appropriate magnetic field, the narrower the effect, the narrower the effect.

(`` Fuel and Combustion '' 51.1984)

This suggests that the magnetic material at that time was mainly due to the ferrite (Fe ₂ O ₃ ) sintered body, which had a magnetic field of about 1000-3000Gs. Mr. Hirama provides a device for processing at high magnetic flux density of 5000-7000Gs or more as a technical background for instant magnetic processing (Japanese Patent Publication No. 6-49192). have. However, this uses the magnetized material of only 10800Gs of samarium cobalt, and its contents are also very complicated and practically expensive, and this method is in direct contact with the passing water. It cannot be used for corrosion.

The most powerful magnets based on recently developed neodymium (Nd atom No 60) materials compensate for this weakness. For reference, a comparison with the former magnet is given in Table 1.

As shown in this table, the neodymium magnet is known as a super magnet, which has about 6 times the magnet density and 37 times the maximum energy, compared to the ferrite magnet used in general water treatment systems. Can

In addition, the activated water quality is the result of providing an optimal environment for microbial growth in the microbial treatment process that forms the center of the circulating filtration system. The remaining problems are concentrated on providing optimal habitat for microbial habitat.

That can be seen by looking at the microbial knowledge. This is briefly described as follows.

Biomass, collectively referred to as microorganisms, ranges from non-cell-producing buses to bacteria, filamentous fungi, and spores, and is said to have many variations in biological activities.

They are broadly classified as aerobic and anaerobic bacteria, and they are known to breed under three principles: feed (nutrient), home (habitat), and enemy (antagonist). The term "feeding" refers to feces or litter, and the term "house" refers to the water, air, matter, ions, etc., in the space of the surface area. In the case of "house", in the case of microorganisms, this food is said to be fierce. It is said that the more susceptible substances in food, the faster the growth of microorganisms is easier to grow (aerobic), and the more difficult to decompose, the more likely they are to have special capabilities (anaerobic).

The propagation of microorganisms is the finding that the three conditions can be stabilized for a long time, and the expansion of the surface area of the media and the inflation of fruit juice will greatly close up.

Sugiura announced that the surface area of charcoal is 200-400m3 / g, which has a large surface area that is not comparable to the average of 20m2 / g of coal, coke or minerals (eg, rock). (炭) (1999) He actually buried 12 120kg charcoal manures in a stream about 2m wide and about 950 people's living wastewater. It is reported that from the month the fish lived. In addition, the life span of two years has elapsed, and it can be seen that there is only a brief point in the experimental result that there was only a little loss of charcoal.

This shows that charcoal has excellent purification ability, and Seoul Metropolitan Government has informed the public about advertisements that can be safely eaten with water purified by charcoal in daily newspaper (Chosun Ilbo 2000.09.26.11 page 11). The inventors were able to confirm that the capacity was excellent as expected by filling it in the filtration tank of the circulating filtration water purification system. Of course, in this embodiment, the utility model patent (No. 0166750) and the no. 10-2000-0068646 and (10-2000-0087663) and the air blower, together with the air blower and the electric neodymium super magnetic field It is the result of using the active water which passed.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

Fig. 1 is an apparatus (2) (4) for separating and removing contaminants from a plurality of aquaculture tanks (1. 2 in the drawing) as the whole wood of the circulating filtration system as shown. After treatment in the microorganism filtration water tank (plural 5-1, 5-2, 5-3.) Of the invention, the minerals of the circulating water must be passed through the mineral housings such as ceramics or elvan, clam shell which are known methods. In order to dissipate the supplemental water mainly coming from (A), the UV sterilization tank (7) and the warming tank (8) process was carried out in a path that was circulated in the breeding tank (1). Figure 2 is a microbial filter tank (5) for carrying out the present invention, the first circulating water of a breeding tank size 20t (diameter 8m. 19 equilibrium) 1 unit. The amount of circulating power related to this was about 5 times a day, about 100 m 3, and the supplemental water was injected with 2 m 3 (1/10). The size of the microfiltration filtration tank (5) was arranged in parallel with three volumes of about 3.3m in length, 3.5m in width, and 3.5m in depth (3.2m in depth) for approximately 24m3 of breeding water.

The amount of oak charcoal (must white oak charcoal) filled inside is filled with about 4 kg (500 mm = 1.2 million m2) at 500 mm thick in the lower layer (12) for anaerobic bacteria, and targeted for aerobic bacteria. The crater 13 was filled with about 2.5 kg of 300 mm thick (surface area 300 × 2500 = 750,000 m 2) to provide sufficient space for microbial habitat by filling in three tanks having this surface area.

When the depth of the lower layer 12 is about 1.1m, the flow rate of 12.7m3 is adjusted to 0.07ℓ / min with the 25mm caliber pump 3 so that the retention flow rate of 181 minutes (about 3 hours) is maintained. It is suitable environment for breeding.

At the same flow rate, the circulating water passes through the upper layer 13, where the performance of the pump 17, which is the energy source of the air blower 20 having a diameter of 50 mm, diffuses 20 m3 of air into the water, thus reducing the residence time. Expected to be 5 hours, the amount of air injected during this time is a whopping 100 ㎥. This is sufficient not only for microbial habitat but also for the release of nitrogen gas from dissolved carbon and ammonia nitriding in water. In addition, the breeding water passing through the supermagnex 18, which is one of the peculiarities of the present invention, in the suction pipe of the pump 17 is instantaneously small in cloister, so that the penetrating power is strong in various mineral bodies, thereby obtaining abundant mineral water. Not only is it effective for microbial cultivation, but the repeated production of active water in three microbial filtration tanks (5) has contributed greatly to the growth of breeding as it results in improved water quality of the entire breeding tank (1).

The operation of the magnet itself, which is the core of the present invention with the above configuration, is extremely simple. Water does not pass through the magnetic field, only the action of physical change. This theory is briefly explained in the professional foresight as follows.

Water molecules combine hydrogen and oxygen molecules at an angle of 104.5 ° (see Figure 3.4). When this water passes through a strong magnetic field, a violent spoofing occurs from 104.5 ° to 95 ° or 190 ° and the original angle At the moment of returning to 104.5 °, the various forms of angular change are repeated and the clusters of water are finely divided and water activation is promoted.

Prior to conducting a 20m3 water tank under the above conditions, preliminary operation was performed for about 100 days for the settlement of various microorganisms in the filled charcoal, and then supplemented with 4000g of 250g flounder. One ton per day, which is half of the weight, 320g weight (3972) in two months 420g weight (3957) in three months was successful at the mortality rate never seen before.

However, recently developed neodymium super-strong magnets are developing new applications for the effect that this action has revolutionized conventional magnet recognition. In addition, this method is an advantage that the extremely simple operation that can be realized by simply attaching to the outer wall of the circulating water pipe to be transported. And the life of this magnet is characterized by showing a semi-permanent powerful power that can not be compared to the seed electromagnet. The activated water is not only to increase the microbial water filtration effect due to the activated foam in relation to the power consumption of the air blower (11) in the enormous amount of air can be blown underwater. As the activity of the whole water is increased, it prevents water deterioration for long-term use, and the purification ability of the charcoal charged in the filtered water tank is also enhanced to exert an increased effect.
